Data Discovery (ECS)
ECS for Data Discovery - Mandatory
These attributes are mandatory for the Earth Observation System Data and Information Core System (ECS) metadata model.
Concept | Description | Dialect (Fit) Paths |
---|---|---|
Resource Contact | The organization or person responsible for answering questions about the resource. | ISO /*/gmd:identificationInfo/*/gmd:pointOfContact ISO-1 /mdb:MD_Metadata/mdb:identificationInfo/mri:MD_DataIdentification/mri:pointOfContact/cit:CI_Responsibility ECHO /*/echo:ArchiveCenter ECHO /*/echo:Contacts/echo:Contact ECS /CollectionMetaDataFile/CollectionMetaDataSets/Collections/CollectionMetaData/Contact[Role='User Services'] DIF /dif:DIF/dif:Personnel[dif:Role='INVESTIGATOR'] SERF /serf:SERF/serf:Personnel |
Abstract | A paragraph describing the resource. Note: This concept is called "Desciption" in Catalog Services for the Web. |

xPath Note: The xPaths included in this table use several wildcards. // means any path, so //gmd:CI_ResponsibleParty indicates a gmd:CI_ResponsibleParty anywhere in an XML file. /*/ indicates a single level with several possible elements. This usually indicates one of several concrete realizations of an abstract object. For example /*/gmd:identificationInfo could be gmd:MD_Metadata/gmd:identificationInfo or gmi:MI_Metadata/gmd:identificationInfo and gmd:identificationInfo//*/gmd:descriptiveKeywords could be gmd:identificationInfo/gmd:MD_DataIdentification/gmd:descriptiveKeywords or gmd:identificationInfo/srv:SV_ServiceIdentification/gmd:descriptiveKeywords. Fit: The fit of the dialect path with the concept is estimated on a scale of 1 = excellent two-way fit, 2 = one-way fit or some other problem, 3 - extension required.
